PETER HARDMAN OF WILLIMANTIC, COllINECTICUT, ASSIGNOR TO THE AMERICAN mn'rnon oF'M'ouN'rING THI tEADJ p Application filed August 5, 1925. Serial No. 48 ,288.

' My invention relates to an improved method of mounting thread samples.

An object of the invention is to provide a novel and improved method which is parti'cularly adapted for use in mounting thread samples "for display purposes. Another'object of the invention is. to pro vide a method of mounting thread samples whereby thread of different sizes may be .10 mounted in separate groups, with the threads in each group arranged sldeby side,

and with the several groups arranged side it by side, spaced equal distances apart and of substantially the same width, irrespective ll"! of the difference in the sizes of the threads.

Another object of the invention is to-pro-- The several features of the invention,

whereby the above mentioned and other objects may be attained, will be clearly understood from the following description and i0, accompanying drawings, in' which,

Fig. 1 is a diagrammatical side view of a portion of a machine which may be employed in carrying out my improved method;

Fig. 2 is a of the same; I

Fig. 3 is a face view of a display card formed in accordance with my invention and the strip from which the card is cut; L0 and y Fig. 4 is a detail rear elevation of a portion of thread selecting and-groupin de-' vices of the machine illustrated in Figs. 1 and 2.

My improved method is (particularly adapted for use in forming the isplay card 2, illustrated in Fig. 3 of the drawings. As shown, this display card is provided with a rectangular backing 4 of paper or cardboard upon which are mounted groups of thread 6 that extend transversely thereof. The threads of each group are arranged side by side'substantially in contact with each other,

plan view, partly broken away,

and the several groups are arranged side by side and equally spaced slight distances apart. The threads in each group are of the same size, but the threads in some of the several groups are, of diiferent sizes. Irrespective, however, of variations in the sizes of the threads in the different groups, the

width of the groups is the 'same, this being accomplished by arranging a less .number of threads in the groups containing the larger sizes; By such an arrangement of the threadsthe several groups of threads are of uniform width and are displayed to equal advantage. r

The threads are secured to the backing of the display card by, lines of adhesive 7 there, being two such lines adjacent each oi the longitudinal edges of the backing.

. In carryin out my improved method, a machine suc as the one described and claimed in my pending application Serial No. 703,047, filed March 31,1924, may be employed. As shown, a' strip or web from which the backing 4 of the. display cards are formed, is drawn from a supply roll 8 over a flanged guide roll 10, through a suitable tensioning device 12, between guiding or registering rolls 14, over a drum-16, beneath a pressure roll 18 acting on the drum, and

from thence to a suitable take-up device comprisinga drum 20. As the web passes over the drum 16, transverse lines of adhesive are supplied to, the outer side of the web, the lines of adhesive being arranged in groups of four, and the distance between the longitudinal centers of each' two adjacent groups of lines of adhesive being equalto the width that it is desired to form the display card 2. These lines of adhesive may be applied by means of a suitable daubing device 22 supplied with glue from the tank 23.

The threads which are to be mounted, are first arranged in groups containing the threads that are to be mounted upon the display cards, the'threads in each group-being arranged in parallel relation in a row, and the several rows or grou s being incllned slightly to the vertical. uch grouping of the thread may be accomplished by a suitof holes 25. As the threads leave the device 24, the threads in each group are brought together as bypassing them beneath a guideirod 26, the inclination of the groups 1 rod 26 the threads thus grouped, are passed over a guiding and tensioning rod 28, then over a suitable compacting or condensing device 30 which compacts the threads in each group closely together in side by side relation, then over a guide rod 32, and then beneath a suitable compacting device 34 which positions them in close proximity to the backing strip as it passes over the drum 16, the compacting device 34 being similar to the device 30 except that its faces slant in one direction so as to insure the threads of each group being closely compacted together in side by side relation. The threads thensimultaneously pass to the backing strip and beneath the pressure roll 18, said -roll applying pressure to the threads to in-. sure their abherence to the strip by means of the lines of adhesive. The threads are par allel to the axis of the strip. Thereafter the completed web is wound up on atake-up drum which is spaced a sufiicient distance from the drum 16 and roll 18 to permit the adhesive to dry before the web is wound up. The selecting and grouping devices 24, and the compacting devices and 34, as well as the other parts of the machine illustrated in the drawings, may be of the construction of the corresponding parts of the machine of my pending application, hereinbefore referred to.

It will be apparent that the completion of the steps of the method above described, results in the threads being arranged in groups and mounted upon the backing strip parallel to the axis thereof, the number of threads-in each group being in accordance with the grouping of the threads on the display cards that may be desired to be produced, the completed web being shown at 36 in Fig. 2 of the drawings. The number of threads in each group varies inversely as the size. Thus it will be seen in' Fig. 4 that there are three threads passing through the right hand set of grouping holes, four smaller threads passing through the next set, and six smaller threads passing through the next group, so that the final groups are of substantially the same Width though the sizes of the threads vary.

After the web and the thread mounted thereon has been wound up on the take-up drum 20, as above described, it may be removed and the web cut transversely on lines extending through the longitudinal centers of each group of adhesive 7 to produce the display card 2. To thus cut up the completed web, a machine such as the one de-- gitudinally, applying transverse lines of ad-.

hesive to one side of the strip, drawing a plurality of threads from points spaced apart, respectively, arranging the threads in groups as they are being thus fed with the threads in each group arranged side by side in close proximity, and with the several groupsarranged side by side and spaced apart, and applying the groups of thread thus arranged to said side of the strip as the strip is being fed, so as to cause the groups of thread to lie longitudinally of the strip and adherethereto. I

2. The method of mounting thread which comprises applying to a strip at regular intervals transverse bands of adhesive, laying upon said strips longitudinally thereof and simultaneously a plurality of threads arranged side by side in groups, and securing them to said strip by said adhesive.

8. The method of mounting thread which comprises producing a series of parallel threads, forming said series into a plurality of compact thread groups, applying to an extended strip at intervales transverse bands of adhesive, and laying the threads of said. groups simultaneously upon said extended strip in contact with said adhesive.

4. The method of mounting thread which comprises producing a series of parallel threads, said series being made up of a plu rality of portions, each portion made up of a plurality of threads of the same size and differing in size from threads in other portions, forming said series into a plurality of thread compact groups of substantially the same width, each group having threads of one size only, applying to an extended strip at intervals transverse bands of adhesive, laying the threads of said groups simultaneously longitudinally upon said extended strip in contact with said adhesive, and, pressing said groups into contact with said adhesive.

In testimony whereof, I have signed my name tothis specification this 1st day of August, 1925. ,l v
